This is a good news that I am talking about not only is this series going to be released in the PS4, which contains a part 4 but they will remaster the 1st and 2nd parts that were released on the pS3 to the PS4 system.
The best news of all is that they will remaster even the Trails of the Sky Games to the PS4 system, and the 4th part of the Trails of the Cold Steel will have a ton of characters that will help Rean meaning that they could be recruited or are in the game they will add characters even Trails of the Sky as well.
